Adding Attributes to all XML Nodes

[cesarcesar]

Howdy,

I have an PHP page that edits XML files. I want ADD a new *id* attribute to all nodes on the page that do not have it all ready. Then i want to delete all of the values of *id* and set them as an incremental 1-x values down the page.

This is the current code i am using to edit specific nodes. Im trying to use DOM, but it doesn't have to be. I just need it to work.

<?php
$content = $_POST['content'];
$id = $_POST['id'];
$node = $_POST['node'];
$explode = explode("_",$node);
 
$dom=new DOMDocument();
$dom->load('sample.xml');
$dom->formatOutput = true;
//echo $dom->saveXML(); // show before file
$allnodes = $dom->getElementsByTagName($explode[0]);
foreach ($allnodes as $nodes) {
    if ($nodes->nodeName==$explode[0] and $nodes->getAttribute('id')==$id) { //
        $nodes->setAttribute($explode[1],$content);
    }
}
$dom->save('sample.xml');
?>

This is the XML file im working with. **NOTE** the missing *id* attributes of the 2nd *child01* node.
